Common issues to watch out for on the 2.0T FSI engine include carbon buildup on the intake valves (leading to rough running and reduced performance), failing coil packs, and oil consumption issues. The Multitronic CVT gearbox (available on some models) can also be prone to failure, so check for smooth operation during a test drive. Suspension components, particularly the control arms, can wear out over time, leading to knocking noises and poor handling. Regular servicing is crucial to mitigating these issues.
